The pump motor works fine. That is to say it spins with power

This is a used carbonator. I have a feeling that I'll have to rebuild
the pump :-(

They guy I bought the carbonator from said it won't pump from a
bucket. I did purge the line of air before trying, and nuthin'.
Everything's pointing to the pump itself. I'm going to pull the
pump off and see what I can do with it. Doubt if I can get any parts
at this time, unless Home Depot or Lowes has something that will work,
ya neer know.
To purge the tank of air, after I pressurized with CO2, I opened the
"soda" valve on the soda gun for a bit. I'll try to pull the
emergency pressure relif valve this time and see if the water gets
First to pull that darned pump.
anyone have a procon pump for sale cheap? cheap is the key word
here, I've already spent way too much on this system :-(
thanks for the help!
